Problem

[bug] Phase 4 gate wiring ships to adopter stubs but agent-rate-limit-gate.sh is absent at v1 — gate is inert and fail-open

From the issue: Phase 4 (#640, PR #1059) wired the agent rate-limit gate into the initiative-driver.yml caller stub. The stub fetches the gate tooling from petry-projects/.github at ref v1. scripts/agent-rate-limit-gate.sh does not exist at v1. v1 is d3d768da, which is 359 commits behind main, and the script is only on main.

Risk

Medium — changes GitHub Actions workflow behavior, which is exercised only post-merge; verify via the affected workflow runs.

Test plan

Tests added/updated: test/workflows/initiative-driver/gate-tooling.bats. Verification: bash scripts/dev-lead-lint.sh (shellcheck --severity=warning) ran pre-commit; the bats suite runs in CI.

Rollback

Revert this PR. No non-revertible side effects (no tags, migrations, or external state).

Monitoring

Watch the affected workflow run(s) in the Actions tab and this PR's Lint check for regressions.

📝 Summary

Summary by CodeRabbit

• Workflow Updates

  • Rate-limit checks now run after concurrency handling, so superseded runs can still be canceled before dispatch checks begin.
  • Gate failures are reported visibly, while dispatch can continue unless the gate explicitly defers it.
  • Gate tooling is retrieved from a fixed, verified version for more consistent workflow behavior.
  • Workflow setup guidance now supports the current access credential and a legacy fallback.

• Documentation

  • Clarified rate-limit behavior and setup steps for enrolled workflows.

Walkthrough

The initiative-driver rate-limit gate now uses pinned tooling and reports missing-script and invocation failures. The workflow remains fail-open for dispatch through continue-on-error. Workflow and standards text document concurrency behavior and the PAT fallback. Bats tests cover gate wiring and stub parity.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to cd621

The change pins the gate tooling to a reviewed commit and makes gate failures visible while dispatch stays fail-open. No concrete merge-blocking risk remains.

Security Architecture Review

Security architecture risk: 🔵 Low · up to cd621

The immutable tooling pin improves integrity and failure visibility, but the workflow still lacks repository context for reading rate-limit history, so ordinary runs are expected to remain ungated. Increased exposure was not established; production token permissions and downstream behavior remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — Compromise of executed tooling could exercise the supplied PAT's actual grants, potentially beyond one adopter repository. The fixed commit limits moving-reference substitution, but the maximum credential scope cannot be determined from workflow permissions alone.

Security Findings and Attack Paths

• inferred — Fail-open dispatch remains an existing exposure, not an established new attack path introduced by this PR. The intended repair still lacks history-repository binding; absent or unreadable history permits dispatch rather than enforcing throttling.

Trust Boundaries and Controls

• observed — Issue-triggered actor and tracking-issue values enter the gate through environment variables and quoted arguments. The executable repository, commit, and central dispatch destination are fixed by the workflow. Tracking-repository identity is explicitly supplied to issue mutation commands, but is not reused for history lookup.

Resilience and Maintainability Implications

• inferred — Breaker escalation is latent in ordinary empty-history execution. If made reachable, its comment and label writes are independently best-effort, and repeated execution can duplicate comments because deduplication reads the issue body while writing the marker into a comment. This is not retained as an active PR concern because current normal execution does not reach that transition.

Hardening Proposals

• proposed — Bind history lookup explicitly to the adopter repository and validate allow/defer behavior in a workspace containing only the nested tooling checkout. Before activating escalation, align marker lookup with its persistence location and validate repeated execution and partial comment/label failures.

Explanation

The changes address the main coding requirements in [#1232]. The stub now uses a full commit SHA, checks for the script, reports a missing script with ::error:: and $GITHUB_STEP_SUMMARY, and removes || true. The header and standards text describe post-concurrency throttling and fail-open dispatch behavior. Bats tests cover these controls. The reviewed evidence does not prove that scripts/agent-rate-limit-gate.sh exists at the pinned SHA, and it does not establish that broodminder-export#145, ContentTwin#469, markets#494, TalkTerm#499, and google-app-scripts#585 were regenerated from the fixed standard.

Code Review

This pull request pins the agent rate-limit gate tooling to a specific commit SHA instead of a moving tag, and adds robust error handling to fail loudly but open if the gate script is missing. It also introduces a new BATS test suite to verify these behaviors. The review feedback focuses on improving the reliability of these BATS tests by replacing generic negations and non-zero exit status checks with explicit assertions of the expected exit status, which prevents false positives from unrelated script errors.

Summary

Pins the initiative-driver gate-tooling checkout to commit SHA cd0b167 instead of the moving tag v1, which was missing the gate script. A missing gate script now fails loudly while the dispatch still runs (fail-open), and the header text is corrected. The change is correct and verified, but 4 review threads are still unresolved and one of them is a real no-op test assertion.

Linked issue analysis

Closes #1232. Acceptance criteria:

• ✅ Script resolves at the fetched ref. Checked via the API: cd0b16751454d2eb3486ec04477d7ee9cc96c425 exists (it is current main), and all three gate files resolve at it: scripts/agent-rate-limit-gate.sh, scripts/lib/agent-rate-limit.sh, standards/agent-rate-limits.json.
• ✅ A missing script is detected. An [ -f ] guard emits ::error::, writes a step-summary line, and exits 1. continue-on-error keeps the job running, and the dispatch != 'defer' guard stays fail-open, as the standard requires (ADR §7).
• ✅ Tooling checkout pinned to a full SHA. The new paragraph in standards/agent-rate-limits.md §3.1 documents how to bump it.
• ✅ Header matches behaviour. The 'AHEAD of the cancel-in-progress' claim is removed, and adoption step 3 now names GH_PAT_DON_PETRY with GH_PAT_WORKFLOWS as the fallback.
• ⏳ Fan-out PRs regenerated. This happens after merge through standards-sync and is out of scope for this PR.

Removing || true is safe: the gate script at the pinned SHA documents that it always exits 0, with the decision passed on stdout and in $GITHUB_OUTPUT. So only a crash will now mark the step failed, which is the intended loud behaviour. The live copy and the standard stub are byte-identical (same blob 609e6c405).

Findings

Blocking (gate 4: unresolved review threads): 4 unresolved gemini-code-assist threads on test/workflows/initiative-driver/gate-tooling.bats (lines 41, 52, 56, 64). The dev-lead pass reported "no code changes were needed" but did not reply to or resolve them.

1. Line 56 is a real no-op assertion. Fix it. ! grep -q 'decision=defer' "$tmp/out" 2>/dev/null is not the last command in the test. Bats does not treat a negated command as a failure under set -e, so this check can never fail. Replace it with run grep -q 'decision=defer' "$tmp/out" followed by [ "$status" -ne 0 ], or touch the file first and assert -eq 1.
2. Lines 41 and 64 work as written. In both, the ! … negation is the last command in its test, so Bats uses its exit status. Reply and resolve, or convert to run …; [ "$status" -eq 1 ] for consistency.
3. Line 52 is fine. [ "$status" -ne 0 ] is backed by the ::error:: and summary-content checks that follow. Tightening it to -eq 1 is optional. Reply and resolve.

Non-blocking nits:

• The pin comment says main @ 2026-10-02, but commit cd0b1675 is dated 2026-09-30. This is cosmetic.
• The gate-error path (the script crashes) relies on the runner's generic 'Process completed with exit code N' annotation, not a custom ::error::. That matches the header's 'fails loudly' claim well enough.

Security: the PAT was already handed to the fetched tooling before this PR; pinning the ref to an immutable SHA narrows that trust boundary. No new secrets, no new third-party actions, and actions/checkout stays SHA-pinned. No security concerns. The run_secret_scanning MCP tool is not available in this session, so this review did no MCP scan; the gitleaks CI check passed.

CI status

All required checks green: Lint, Lint and bats, bats (×2), ShellCheck, CodeQL / Analyze (actions, python), SonarCloud (Quality Gate passed), Secret scan (gitleaks), Agent Security Scan, AgentShield, duplicate-decl-gate, dependency-audit. The cancelled and skipped runs (dev-lead dispatch/resume/ci-relay, dependabot-automerge) are automation lanes, not checks. CodeRabbit is pending and cubic is still in progress; both are third-party advisory reviewers.

Summary

Re-review at the same head commit (cd62129), with no new commits since the cycle-1 fix request. The fix is correct: the gate-tooling checkout is pinned to SHA cd0b167, which contains all three gate files. A missing gate script now fails loudly while the dispatch stays fail-open, and the header text is corrected. However, the 4 gemini-code-assist review threads are still unresolved, and the no-op assertion at gate-tooling.bats:56 has not been fixed.

Summary

At the reviewed SHA cd62129 the gate call has no --repo, so its history lookup fails, it silently allows, and the rate-limit gate stays inert. The PR has since moved to 8b8759d, which adds --repo, a loud error path and stronger tests. I checked those fixes and they look correct from a security standpoint: the tooling pin is a signed main commit (identical to main) containing all three gate files, and the gate script accepts --repo. Escalating rather than approving because this verdict is bound to a stale SHA and every required check on the new head is still pending; a fresh cycle at 8b8759d with green CI should be approvable.

Summary

Fixes #1232. The initiative-driver stub fetched the rate-limit gate tooling at tag v1, which does not contain agent-rate-limit-gate.sh, so the gate never ran. This PR pins the tooling checkout to a full commit SHA (cd0b167), passes --repo so the gate reads the caller's run history, and swaps the silent '|| true' for a loud failure that still lets the dispatch run (::error:: annotation, step summary, step marked failed, continue-on-error keeps dispatch going). It also corrects the header, documents the pin in agent-rate-limits.md, and adds a bats suite. The live copy and the standard are byte-identical (same blob 1c7c765b2). Every finding from the prior cascade review (at cd62129) is resolved at 8b8759d, and all required checks are green.

Linked issue analysis

#1232 acceptance criteria:

• Gate script resolves at the fetched ref: done. I confirmed that scripts/agent-rate-limit-gate.sh, scripts/lib/agent-rate-limit.sh and standards/agent-rate-limits.json all resolve at cd0b167, and that the gate parses --repo (line 413).
• Missing script is detected: done. A [ -f ] guard emits ::error:: and a step-summary line and exits 1. Gate errors are surfaced too, through || { rc=$?; ...; exit $rc; }.
• Tooling checkout pinned: done. It uses a full SHA, with the bump procedure documented in agent-rate-limits.md.
• Header matches behaviour: done. The 'AHEAD of the cancel-in-progress' claim is removed, and adoption step 3 now names GH_PAT_DON_PETRY with GH_PAT_WORKFLOWS as fallback.
• Fan-out PRs regenerated: this is post-merge standards-sync work and can't be shown in this PR. See the note under Findings.

Findings

Prior review findings (cascade at cd62129):

• major, gate call missing --repo: resolved. 8b8759d adds --repo "$ARL_TRACKING_REPO", the pinned gate supports it, and a bats test covers it.
• major, CI pending on the new head: resolved. Every required check (SonarCloud, CodeQL, AgentShield, Detect ecosystems) is green at 8b8759d, and so are Lint, ShellCheck, bats, gitleaks and the Agent Security Scan.
• minor, the gate can still allow silently with exit 0 when run history can't be read: this is fail-open by design and documented. Not a regression; non-blocking.
• minor, the decision=defer assertion in the missing-script test is weak: non-blocking test-quality nit.

New / remaining notes (non-blocking):

• nit: The stub header says the concurrency group 'cancels a superseded run before any step (gate included) executes'. agent-rate-limits.md now says, more accurately, that it 'may cancel a superseded run after its steps have started'. The two wordings should eventually agree. This is documentation only.
• info: The body says Closes #1232, but acceptance criterion 5 (regenerating the stalled fan-out PRs) happens after merge via standards-sync. Whoever owns #1232 may want to confirm the fan-out PRs refresh before treating it as fully done.
• info: Security posture improves. The PAT-bearing tooling checkout moves from a moving tag to an immutable SHA. The checkout action stays SHA-pinned, persist-credentials stays false, and untrusted values reach the script through env: rather than ${{ }} interpolation in run:. No new secret surface.
• Secret scan (MCP): the run_secret_scanning tool is not available in this environment, so it was skipped. The gitleaks CI check passed.
• All review threads (gemini-code-assist, cubic) are resolved, and there are no unanswered human questions.

CI status

All required checks pass at 8b8759d: SonarCloud, CodeQL, agent-shield / AgentShield and dependency-audit / Detect ecosystems. Lint, ShellCheck, bats, Lint and bats, Secret scan (gitleaks), Agent Security Scan, duplicate-decl-gate, Analyze (actions/python) and the AGENTS.md self-check also pass. Two runs are still queued: dependency-audit / npm audit (not required) and pr-auto-review / check-and-dispatch, which is this review's own run.

Summary

Confirms the triage assessment for #1232. The initiative-driver stub (canonical copy plus a byte-identical live copy) now checks out the gate tooling at a full commit SHA instead of the moving v1 tag, which did not contain the gate script. A missing script or a gate error now fails the gate step loudly (::error:: + step summary + non-zero exit) instead of being hidden by || true. continue-on-error keeps the dispatch fail-open. The step also passes --repo, and the header text is corrected. Note: the PR was already merged (2026-10-02T18:26:18Z) at this same head SHA, so this verdict is a confirmation only.

Linked issue analysis

Closes #1232. Acceptance criteria:

• Script resolves at the fetched ref: confirmed. Pinned SHA cd0b1675… exists on main (1 commit behind main) and all three gate files resolve there: scripts/agent-rate-limit-gate.sh, scripts/lib/agent-rate-limit.sh, standards/agent-rate-limits.json.
• Missing script is detected: confirmed. An explicit [ -f ] check emits ::error:: and exits 1, and a bats test runs the extracted step script to prove it.
• Checkout is pinned: confirmed. It uses a full 40-char SHA, and the bump procedure is documented in standards/agent-rate-limits.md.
• Header matches behaviour: confirmed. The claim that the gate runs AHEAD of the concurrency group is removed, and adoption step 3 now names GH_PAT_DON_PETRY.
• Fan-out PRs regenerated: this happens through standards-sync after merge, so it is out of scope for this PR.

Findings

No blocking findings.

• Non-blocking (docs): the stub header says the concurrency group cancels a superseded run "before any step (gate included) executes". standards/agent-rate-limits.md says it "may cancel a superseded run after its steps have started". The standards doc is the more accurate of the two, since cancel-in-progress cancels the earlier, possibly already-running, run. Consider making the wording match in a follow-up.
• Verified: the gate script supports --repo <owner/repo> (it is passed to gh run list --repo), so the new flag is valid.
• Verified: || { rc=$?; …; exit "$rc"; } correctly keeps the gate's exit code under set -e.
• Security: no new secret handling. The PAT goes to first-party code at an immutable SHA, which is stronger than the moving tag it replaces. persist-credentials: false is kept, and the actions/checkout pin is unchanged.
• All review threads (gemini, cubic) are resolved, and there are no unanswered human questions.

CI status

All required checks pass: Lint, bats, ShellCheck, CodeQL (actions/python), SonarCloud (Quality Gate passed), gitleaks, AgentShield, Agent Security Scan, and dependency-audit. Some dev-lead orchestration jobs show CANCELLED or SKIPPED; these are superseded automation runs, not test failures.
